Green flare compositions

Abstract

Improved green flare compositions which retain acceptable dominant wavelength and purity and produce efficiencies up to about 11,000 cd-s/g. The flare compositions contain magnesium, barium nitrate, boron and a binder.

I claim: 
     
       1. A green flare composition free of chlorine containing compounds consisting essentially, by weight of between 25 and 40 percent of magnesium, between 5 and 15 percent of boron, between 40 and 55 percent of barium nitrate, and about 5 percent of an epoxy binder. 
     
     
       2. A green flare composition free of chlorine containing compounds which, upon burning provides a high luminous efficiency and high luminous power, consisting essentially, by weight, of about 39 percent of magnesium, about 6 percent of boron, about 50 percent of barium nitrate, about 4 percent of an epoxy resin and about 1 percent of a polyamine.
